  • Publication number: 20220258778
    Abstract: A system and method are provided for spacing railcars of a train apart from each other with a predetermined gap in between. Embodiments include a railcar spacing tool having a hydraulic cylinder with brackets at opposing ends for contacting the frame of each of a pair of adjoined adjacent railcars to be spaced from each other, and a cylinder support frame attached to the cylinder and movably attached to a support vehicle such that the support frame is movable from a retracted position to an extended position where the brackets are between the frames of the pair of railcars. After moving the cylinder support frame to the extended position, the brackets are positioned in contact with the railcar frames, and the cylinder is engaged to create the predetermined gap between the railcars. The railcars' brakes are applied to preserve the gap, and the spacing tool is then removed.
